Abstract

Se describen los sistemas y métodos relacionados con una señal de sincronización (18) particularmente muy adecuada para dispositivos inalámbricos (22) en un área de cobertura extendida (16) de una célula (14) de una red celular de comunicaciones (10). En una modalidad, una estación base (12) transmite una señal de sincronización (18) que incluye múltiples repeticiones de un bloque de sincronización básico durante un tiempo de coherencia de un canal de enlace descendente sobre el cual se transmite la señal de sincronización (18). Las múltiples repeticiones del bloque de sincronización básico durante el tiempo de coherencia hacen posible la combinación coherente durante la detección de la señal de sincronización (18) en los dispositivos inalámbricos (22) localizados en la red celular de comunicaciones (10) Esta combinación coherente hace posible, por ejemplo, que los dispositivos inalámbricos (22) localizados en un área de cobertura extendida (16) de una célula (14) servida por la estación base (12) se sincronice a una célula (14) utilizando una señal de sincronización más corta (18) que aquella que se requeriría si solo se utilizara combinación no coherente.
